They are pretty non resonant and there is no way the boxes can flex. The bracing is as you put it "over engineering" but It wasn't that much trouble as everything went together like a jigsaw puzzle.
My existing system is all Pendragons but since I couldn't fit all 7.2 in the room I stacked a pair of pendragon surrounds on top of the mains in a reference speaker configuration.. Not ideal 7.2 surround setup but what I have to work with space wise & Seemed to be about the right height of a central axis for the configuration.
When I get a HT room they will be taken off of my mains and placed midway in the room for a true 7.2 configuration and my CV5000 will be placed in a rack mounted closet... I didn't realize how loud the fans would be as I have fans cooling my marantz and entertainment center and they are quiet... I think I completely understand why you went with 8 of these dayton HOs... They are terrific and very musical subs much better than my PB13U's. I would like to hear your system sometime at a subwoofer shootout. I bet yours sound insane with 8 packed in a HT room! I think though, currently, my room can hit and sustain reference levels that even Archea would approve of.... Just wish stuff would stay on my walls. I collapsed a cabinet shelf of dishes way back in my kitchen this afternoon watching Thor in my living room. I can't imagine the LFE of some systems posted in this thread .... I think I need that dedicated room soon
I'm glad you like them!! It's been a while since we talked, remember I don't have the Dayton's I have the Stereo Integrity drivers. However, what pushed me over the edge into DIY was hearing my friends dual opposed Dayton HO sub he built in my room. I knew I had to go that route because the sound quality was every bit as good as a Seaton Submersive but with more output and of course cheaper. So, I figured I'd buy Dayton's. Well, right at that time I ran across a group buy for SI drivers. I looked into the SI drivers and everyone that had heard the Dayton's and the SI's said they sounded the same, and the output was also pretty much identical so I went with the group buy SI deal.
Currently I only have 4 of the subs because Archaea is borrowing the other 4 to compare with his dual Caps. He got a really good deal on 4 very nice sealed enclosures and is trying to decide what to do (stick with caps, go all out and get 4 LMS 5400 drivers, or 4 Dayton/SI drivers).
I watched the new Star Trek movie with all 8 subs just before he took the 4 subs and then again yesterday I watched a lot of the movie again with 4 subs. 4 subs still has an amazing amount of output. I did notice that on a couple of real low heavy bass scenes there was that slight "chirping" sound which I've come to learn is the amp clipping. This is running the master volume at 5 under reference with the subs way hot and a house curve, so tons of output before this chirping sound.
So, if you ever hear the chirping sound I'm talking about that's what it is, just the CV clipping. It will probably be harder for you to clip the amp though since I assume you are running 2 drivers off of each channel of the CV? I haven't taken the time to re-wire my subs that way, I still have 4 running off of one channel. If I get around to it I want to run 2 drivers off of each channel and see how much more I can push it before I hear the amp "chirping".
If you ever plan to be in the KC area let me know, I love having people over for demo's and you could check out Archea's setup too.
